CHANGELOG.md

@@ -12,14 +12,15 @@ and this project aspires to adhere to [Semantic Versioning](https://semver.org/s
 
 #### Blueprint
 - Added `conduit::blueprint::<mpi>::mesh::state()`, `conduit::blueprint::<mpi>::mesh::cycle()`, and `conduit::blueprint::<mpi>::mesh::time()`, utilities for getting state information from meshes.
+- Added `conduit.blueprint.mpi`, `conduit.blueprint.mpi.mesh`, and `conduit.blueprint.mpi.mesh.examples` modules to the Python interface.
 
 #### Relay
 - Added h5z-zfp compression support to relay io hdf5 methods.
 - Added `conduit::relay::<mpi>::io::blueprint::generate_root_filename()`, which takes the same arguments as `save_mesh` or `write_mesh` and produces the name of the root file that would be generated by a call to `save_mesh` or `write_mesh`.
 - Added `conduit::relay::mpi::memory_usage` and `conduit::relay::mpi::memory_stats` helpers.
+- Added `conduit.relay.mpi.io` and `conduit.relay.mpi.io.blueprint` modules to the Python interface.
 - Added `v1120` and `v1140` options to hdf5 libver settings to support 1.12 and 1.14 libver upper range.
 
-
 ### Changed
 #### Conduit
 - Changed Conduit memory handler callbacks from function pointers to `std::function` objects, allowing users more flexibility in dealing with different memory spaces.
